Golf courses are a special animal. On the one hand, it's a sport built in nature, designed to be played on long, emerald fairways. Golfers appreciate the natural elements - the grass, the sand, the water - it is vital to the art of the game. On the other hand, while golfers are dependent on nature to play their sport, they need that nature to be curated and controlled and nature tends to fight back. One of nature's strongest armies are weeds. Course managers are waging constant battle on these persistent threats, often with chemical warfare, which can run contrary to a deep appreciation of nature. But, new research is showing nature may be able to fight itself in the form of fescue.
